Plug in 1 for n and solve, then plug in 2, and so on until you get to 3(6)-1=17
I can't tell what the numbers are on the first one but you got the second one right, and the last one would be different it would be 24 I believe.
Angle b will be 34 degrees because angle b and the other angle that is 34 degrees are vertical angles!
G = gallons d = days
10g = 3d
?g = 1d
1g = ?d
-------------
for gallons in a day, divide 10g = 3d by 3
d = 10/3 gallons
3 and 1/3 gallons in a day
---------------
for days per gallon, divide 10g = 3d by 10
g = 3/10 days
1 gallon lasts 3/10 of a day
78 rounded to the nearest tenth is 80
